HAT-PIN.

To all whom t may concern Be it known that I, ALEXANDER B. KoxERNo'r, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and useful Hat-Pin, of which the following is a specification.

This invention has reference to improvements in hat pins and its object is to provide a hat pin which may be shortened or lengthened as needed, and will be positively locked in the adjusted positions, and will automatically assume the elongated position when released from the locking means.

The invention comprises a head member and a shank member in telescoping relation, the shank member being constantly constrained toward the projected position, and means are provided whereby the shank member may be manipulated from the end of the head remote from that entered by the shank member, and furthermore the constraining' means for proj ect-ing the pin is so arranged as to tend to move the part of the pin controlled thereby into the locked position, so that in order to adjust the pin toward the projected position it must be held against the action of constraining means tending to lock it and released to the action of the same means in a direction to project the pin.

The invention will be best understood from a consideration of the following detailed description, taken in connection with the accompanying drawings forming a part of this specification, and it will be further understood that while practical forms of the invention are disclosed in the drawings, these practical forms are but examples of other practical forms which the invention may assume, wherefore the invention is not limited to any strict conformity with the showing of the drawings.

In the drawings Figure 1 is a plan view of a pin constructed in accordance with the present invention. Fig. 2 is a longitudinal central section thereof. Fig. 3 is a displayed'view of the movable member of the head of the pin to which member the shank of the pin is secured. Fig. 4 is a section on the line 4 4 of Fig. 2. Fig. 5 is a section on the line 5 5 of Fig. 2. Fig. 6 is a section on the line 6 6 of Fig. 2. Fig. 7 is a longitudinal section of a pin of some- Specicaton of Letters Patent.

what modiied construction. Fig. 8 is a plan view of the pin shown in Fig. 7 with so-me parts broken away. and in section. Fig. 9 yis a section on the line 9 9 of Fig. 8. Fig. l0 is a section on the line 10 10 of Fig. 7 Figs. ll and 12 are perspective views of details of the invention.

Referring to the drawings, there is shown a head member 1 and a shank member 2, the head member being designed to remain exterior to a hat when the shank member 2 is moved into the hat after the usual manner of applying hat pins. At that end of the head member l through which the shank 2 projects there is app-lied a plate 3 and this plate has at appropriate points, preferably diametrically opposite, spurs 4 so disposed that when the head member is brought into contact with a hat and given a rotative movement about its longitudinal axis, the spurs will enter the hat and draw the plate 3 into engagement therewith, thereby locking the head member to the hat as by a screw, and the head member may be readily removed from the hat by a reverse rotative movement thereof.

The head member 1 is sho-wn as of general cylindrical shape and elongated, and extending throughout the greater portion of the length of the head member is an axial bore 5, so that the head member is in effect a cylindrical shell with the bore opening through the end remote from that to which the plate 8 is applied. While the head member is shown as cylindrical in shape it will be understood that its exterior may be of any desired ornamental shape, either cylindrical or polygonal, or of any configuration which the designer may desire. Extending through one side of the head member longitudinally thereof is a slot 6, one long wall of which is provided with a series of notches 7 shown as regularly disposed, but regularity of spacing of the notches is not mandatory, although preferred. This slot is continued to the end of the head member 1 remote from that to which the plate 3 is applied. At the open end of the head member there is applied a band 8 serving to bind this portion of the head member against spreading.

The head member is designed to receive a carrier for the shank member 2, the carrier being movable longitudinally of the head threaded extension 25.

member' considering the latter as being held against movement, and although this shank carrying;1 member is functionally the same in the two structures shown in the drawings, it litters somewhat in construction in the torni shown in Fig'. 1 and associated iigures 't nn that shown in Fig'. 7 and associated lionney while in both forms the head member is substantially the same. In the form shown in Fin'. 1 and associated figures the pin shank is made fast at the butt end to a cylindrical block having' the end remote lroni the pin reduced in diameter, as shown at 10, and entering` this reduced portion axially is a threaded socket 11, while at diameti.ically opposite points on the enlarged portion of the block 9 there are longitudinal tonnjues 12, the latter beinr adapted to sin'iilarly placed longitudinal grooves 13 formed in the inner wall ot' the head member 1. There is also provided a sleeve l-lwith a central interior web 15 from one le ot which projects a screw 16 adapted to the socket 11, while the reduced portion l0 oit the block 9 is adapted to the interior ot' the sleeve lele on that side carrying' the screw 1G. lhe other side of the web 15 is formed with a plug- 17 while that portion of the sleeve about the plus; 17 has a suitable number' ott screw holes 18 formed therein. Adapted to the end ot the sleeve carrying;` the plus` 17 is the reduced end 19 of a mem.- ber 90 adapted to the interior of the head 1 and constituting' the main portion of the shank carrying` member. The body or main portion ot the shank carrying` member may be .in the form oi an elongated solid block, as indicated in the drawings, or otherwise termed, and when the reduced end 19 is introduced into the sleeve 14. the plus; 17 enters an axial recess Q1 in the reduced portion 1a, while screws Q2 extending' through the screw holes 1S and into the reduced portion 1f) serve to hold the parts together, so that the movable member is in ell'ect a single member, although made up ot several pieces. Projecting radially from the sleeve 1x-lis a stud 23 adapted to extend irough the slot t3 and engage in any one of ie rece :es 7. That end ot' the body meml fa' zu remote 'from the reduced portion 10 is t'ormed with. a socket Qlhavine; a threaded continuation Q5 axial to the body niember and adapted to the end ot the body member containing' the socket 2-1- is a cap block Q6 having` a central extension 27 shaped to enter the socket :211e and by making' both the extension and the socket 2l of sanare or other mln-circular shape the cap member 26 is 'prevented trom turning` relative to the body member Q4. The cap is ired to the body member by a screw @il uch may extend axially through the cap 2G and lthe extension 27 and enter the rlhe length of the body member is such that when the cap member QG, which is ot sutlicient diameter `tor the purpose, engages the end oi the body member 1 remote from that entered by the shank 2, the block 9 is close to the end of the head 1 traversed by the shank 2, and the pin or stud Q?) traversins; the slot G is in engagement with that recess 7 nearest to the said end ot the head traversed by the shank Fast to the block 9 is one end of a spring); 29 and the other end of this spring' is fast to a plate 30 preferably, though not necessarily, of skeleton type, which plate traversed by the shank 2 and carries a suitable number of short pins 31 exten di ng through :appropriate'passages in that end of the head member 1 traversed by the shank 2, and through matching passages in the plate 3, outside otl which the pins 31 are headed, thereby constituting` rivet connections holding' the skeleton plate 3() in engagement with the corresponding end oit the head l. The normal tendency ol' the spring Q9 is to maintain the movable member with the cap 26 against the corresponding' end oi the head 1, but this spring will yield to a suitable torce permitting the cap member to be moved away from the head 1, the shank carrier comprising' the body 20, the sleeve 1st and the block 9 following', this resulting' in the indrawing of the shank 2 with respect to the head 1, while the sin'infg' 2) is extended by this operation. The spring' 29 is also so arranged as to be under some torsional stress,A wherefore it tends constantly to rotate the shank carrying* member in a direction to torce the stud 23 yinto a recess 7 and to there maintain it so that in order to withdraw the stud E23 from a rec-ess, the shank carrying' member must be ,given a slight rotative movement in opposition to the normal tendency ot the spring 29. All the recesses 7 are inclined toward the end of the head member 1 carrying the plate 3, and, therefore, the combined retractive and twisting action of the spring 29 maintains the stud 23 firmly in a notch 7.

The structure shown in Fig. 7 and associated figures differs from that shown in Fig. 1 and associated figures only in that end of the movable member carrying the shank where the shank is attached, and the description ot the other' parts with particular reference to Fig. 1 and associated lignres applies with equal force to the structure shown in Fig. 7 and associated figures and the same reference characters in so far as they apply are used throughout. 1n the structure shown in Fig. 7 and associated iigures there is body member 20a correspondingto the body member :20 ot the previously described construction, and this body member 20a receives the butt end of the pin shank 2 at one end, wherefore in this construction the member 20l becomes the shank carrier or shank carrying member. Close to that end of the body member 20a receiving the pin shank 2 there is formed a circumferential groove 32 in which is lodged a ring 33 provided with a short circumferentially arranged slot 34 and with diametrically opposed tongues l2a corresponding to the tongues 12 of the previously described construction. Extending through the slot 34 is a stud 35 radiating from the body member 2Oa at a point about midway of the length of the groove 32, and this stud extends through the slot 6 in the head 1 and engages in any one of the recesses 7 In the position of the parts shown in Figs. l, 2 and 7, 8 the shank 2 is in the position of greatest projection with reference to the head 1 and the operator by properly grasping the head l may force the shank 2 through a hat until the prongs 4l are brought into engagement with the hat, when a slight twist o the head in the proper direction will cause these prongs to anchor in the hat, thereby holding the pin securely in position against accidental displacement. It' the length of the shank 2 with relation to the breadth of the hat is suitable, then the pin may be used as an ordinary non-adjustable hat pin. Suppose, however, that the shank 2 is too long for the particular hat, then the operator by grasping the cap 26 which has its margins sutficientlv projecting beyond the head 1 t0 admit of grasping, pulls upon the cap 26, while at the same time holding the head l and simultaneously giving the cap 26 a slight twist to unseat the stud 23 or 35 as the case may be from the notch 7 with which it is engaged. Pulling on the cap 26 in the proper direction causes the expansion o1 tne spring 29 against its normal tendency until the shank 2 has been retracted to the desired extent, when the cap 26 may be turned or allowed to turn under the action of the spring 29 in the proper direction to cause the stud carried by the body member to enter the desired one of the notches 7 whereupon the pin with the protruding shank shortened is ready for application t0 the hat in a manner already described.

The hat pin of the present invention is adapted for use where the point of the shank 2 does not protrude through the side of the hat remote from that where it enters the hat, but is brought into engagement with a suitable resisting medium which may simply consist of the wall of the hat if sufliciently resistant. Under such circumstances the spring 29 will yield to permit a movement of the head 1 along the shank 2 until the prongs 4 may be brought into engaging relation with the hat and then by a twisting motion the head l is locked to the hat with the pin under slight longitudinal strain suicient to prevent the movement of the head 1 along the shank, and the pin is therefore securely locked to the hat, although readily removed therefrom by a purposely applied manipulation of the pin structure.
